Acertain make of car is available in 5 body types, 4 colors, and 3 kinds of upholstery. how many cars would a dealer have to keep in stock to be able to show his complete line to prospective customers?

So there's 5 body types each with 4 colors. 5x4 is 20. For each of these 20 cars there is 3 kinds of upholstery. 20x3 is 60. Therefore, the dealer would need a minimum of 60 cars to show his complete line. Hope this helped!
